/ 03 марта 2020

Я работаю над запросом, в котором у меня есть 2 левых соединения, но у меня только 1 одно подмножество, если в другом есть данные. Это включает либо основанные на записях.

Я ищу, чтобы получить результаты 'b' или набор результатов 'исключений', но не оба. Так оно и есть в настоящее время, я получу либо или.
